Das Steuergerät
Eine derartige Startanlage ist wegen der erforderlichen zwei P.elais relativ teuer und bedarf außerdem einer relativ komplizierten Verdrahtung.Such a starting system is because the required two P.elais relatively expensive and also requires one relatively complicated wiring.
Es ist daher die Aufgabe der vorliegenden Erfindung, eine Schalteinrichtung für eine Startanlage eines Kfz zu schaffen, die wesentlich einfacher aufgebaut und kostengünstiger ist.It is therefore the object of the present invention a switching device for to create a starting system of a motor vehicle that is constructed much easier and cheaper is.
Gelöst wird diese Aufgabe gemäß der Erfindung durch die im Patentanspruch 1 angegebenen Merkmale. Weitere Ausgestaltungen. der Erfindung sind Gegenstand von Unteransprüchen.This object is achieved according to the invention by the features specified in claim 1. Other configurations. the invention are the subject of dependent claims.
Der wesentliche Gedanke der Erfindung besteht darin, die Schalteinrichtung mittels einer Transistoranordnung zu realisieren, bei der ein Transistor von einem Steuergerät angesteuert wird, um einen Startermotor einzuschalten. Der Transistor dient dabei als elektrischer Schalter zum Durchschalten der Stromversorgung auf den Startermotor bzw. auf ein Starterrelais. Zur Überprüfung der Funktionsfähigkeit des Transistors sind ferner Diagnosemittel vorgesehen. Transistor und Diagnosemittel können als integrierte Schaltung realisiert sein. Die erfindungsgemäße Schalteinrichtung ist daher sehr einfach und kostengünstig herzustellen.The main idea of the invention consists of the switching device by means of a transistor arrangement to implement, in which a transistor is controlled by a control unit to turn on a starter motor. The transistor serves thereby as an electrical switch for switching the power supply on the starter motor or on a starter relay. To check the Functionality of the Transistors are also provided with diagnostic means. Transistor and Diagnostic tools can be implemented as an integrated circuit. The switching device according to the invention is therefore very easy and inexpensive to manufacture.
Gemäß einer bevorzugten Ausführungsform der Erfindung ist ein zum ersten Transistor in Serie geschalteter zweiter Transistor als Redundanz vorgesehen, wodurch eine wesentlich bessere Funktionssicherheit der Schalteinrichtung erreicht werden kann.According to a preferred embodiment of the Invention is a second transistor connected in series with the first transistor Transistor provided as redundancy, which makes a much better Functional reliability of the switching device can be achieved.
Eine mögliche Realisierung von Diagnosemitteln zur Überprüfung der Funktionsfähigkeit der Transistoren ist ein parallel zum Ausgang der Transistoren geschalteter Spannungsteiler, der bei Normalbetrieb (beide Transistoren funktionieren ordnungsgemäß) an einem Mittenknoten zwischen den beiden Transistoren ein Spannungsfenster vorgibt. Ist einer der Transistoren durchlegiert (Kurzschluß) so ändert sich die Spannung an einem Diagnoseknoten der Schalteinrichtung und die Fehlfunktion eines der Transistoren kann vom Steuergerät festgestellt werden.A possible implementation of diagnostic tools to check the operability of the transistors is connected in parallel to the output of the transistors Voltage divider that works during normal operation (both transistors work properly) on one A voltage window in the middle node between the two transistors pretends. If one of the transistors is alloyed (short circuit), then changes the voltage at a diagnostic node of the switching device and the Malfunction of one of the transistors can be determined by the control unit.
Die Diagnosemittel zur Überprüfung der Funktionsfähigkeit der Transistoren umfassen neben dem Spannurgsteiler vorzugsweise auch einen Widerstand; der an einem Hauptanschluss (D, S bzw. C, E) und dem Steueranschluss eines Transistors angeschlossen ist. Wird der Hauptanschluss über eine Widerstandsanordnung auf die Steuerleitung zurückgeführt, kann die Steuerleitung gleichzeitig als Diagnoseleitung genutzt werden.The diagnostic tools for checking the functionality in addition to the voltage divider, the transistors preferably comprise also a resistance; on a main connection (D, S or C, E) and the control terminal of a transistor is connected. Becomes the main connection over a resistor arrangement can be traced back to the control line the control line can also be used as a diagnostic line.
Das Steuergerät lässt vorzugsweise nur dann einen Start des Motors zu, wenn die Transistoren der Schalteinrichtung einwandfrei funktionieren.The control unit preferably only leaves one Start the engine too when the transistors of the switching device work flawlessly.
Zur Erhöhung der Schaltschwelle der Transistoren kann in den zu den Transistoren führenden Steuerleitungen jeweils eine Diodenanordnung vorgesehen sein.To increase the switching threshold of the Transistors can each in the control lines leading to the transistors a diode arrangement can be provided.
Die erfindungsgemäße Schalteinrichtung kann entweder unmittelbar mit einem Startermotor verbunden oder an einem Starterrelais angeschlossen sein, welches die Stromquelle auf Anforderung mit dem Startermotor verbindet.The switching device according to the invention can either directly connected to a starter motor or to a starter relay be connected, which the power source with on request connects the starter motor.
Die erfindungsgemäße Schalteinrichtung kann ferner in den Startermotor mit integriert sein (Anbaulösung) oder außerhalb des Startermotors angeordnet sein (Wegbaulösung).The switching device according to the invention can also be integrated in the starter motor (mounting solution) or outside of the starter motor must be arranged (path solution).
Vorzugsweise ist die erfindungsgemäße Schalteinrichtung in einem Bürstenplattenmodul des Startermotors integriert.The switching device according to the invention is preferably in a brush plate module of the starter motor integrated.
Die Erfindung wird nachstehend anhand der beigefügten Zeichnungen beispielhaft näher erläutert. Es zeigen:The invention is illustrated below the attached Exemplary drawings closer explained. Show it:
